Ok I've been using the zymol cleaner wax for a long time now. I'm pretty happy with it but after reading a little about Collinite from this site, which I believe is the most scientifically unbiased forum on the web, I decided to go out and buy some. There's a Harbor Freight near me and I always passed up on this wax just because it looks so cheap in it's round little bottle with it's child proof cap, I bought 845 Insulator Wax. I've so far used it on my motorcycle. And I can tell you I've always noticed when waxing plastic things they tend to build up a static charge. Wax insulates the surface, making a kind of dielectric layer allowing my bike to build up a charge. I've noticed that it seems the higher the quality the wax the greater the charge gets on my bike when I polish it. Well I can tell you Insulator Wax lives up to it's name, and it also improves the look of the paint, not as good as the Zymol with it's amazing scratch filling and removal capability but better than any Turtle Wax and nicer than Meguiars NXT. My bike shocked me pretty bad, I've never had a shock so bad from waxing before so I can pretty much assume that my bike is very well waxed. And by other reviews I can see that my little observation is correct. I'm now a Collinite convert.
I personally avoid Meguiars wax because it feels gritty to me. I test all my waxes by applying a small amount between my fingernails and rub them back to back, if I feel grit I know it's damaging my paint. I also test it by polishing a fresh cd-r with it. Meguiars gold class is the worst offender in this case gritty and leaves scratches on a cd.
